Motion simulator chair
A motion simulator chair has a base and a seat. An actuator assembly is between the base and the seat, the actuator assembly including a frame connected to the base, a carrier connected to the seat. A linear actuator is operatively connected to the frame and to the carrier by a mechanism, the linear actuator operable to cause a movement of the carrier relative to the frame, the movement being at least partially vertical. A direction of movement of the linear actuator lies in a transverse plane that is between 15 degrees and 165 degrees from a vertical frontal plane of the motion simulator chair.
